The Berliner Energieagentur provides a broad variety of consulting and contracting services touching its main points of interests: energy efficiency and renewable energy. The links listed below provide you access to our reference projects and plants plus further information on contact persons and documents available for download.

Operation Contracting

Plant or energy supply contracting means that an energy service company (ESCO) as energy service provider takes over the energy supply of a building, mainly supply of thermal heat and hot drinking-water, at its own economic risk.

Lighting

Electric light means quality of living and is the basis of modern life. However, the illumination of public spaces causes huge cost of energy production and, in Germany, results in CO2 emissions of more than two million tons per year.

Procurement

Reduce costs – save resources – acquire customers: "Green procurement" is becoming an issue more and more for professional purchasers from industry and commerce and the authorities. The public authorities, in particular, are asked to consider the long-term consequences in their purchasing strategy.

Biogas

As regards calorific value, there is no difference between biogas and conventional natural gas. However, while natural gas is a fossil fuel with limited resources, biogas is produced from renewable resources and therefore available in unlimited amounts.

CHP units

CHP units are miniature power plants using the combined heat and power (CHP) generation principle to produce heat and power locally and, if required, also to provide refrigeration.

Energy efficient modernisation

Old heating, minimal insulation, windows and doors that let in draught. Still, millions of buildings in Germany are real energy wasters. Given this situation, modernisation in respect of energy efficiency may reduce energy consumption by more than two thirds.

Energy Efficiency

Germany is the global leader in the field of efficiency technology. However, there are chances not only in export but especially in the application in domestic markets.

The measure of success in this area is energy productivity.

Energy Service Contracting

Energy service contracting (ESC) is a partnership between a public authority or an enterprise and an energy service company (ESCO) aiming to reduce the cost of energy supply. At its own economic risk, the energy service provider as the ESCO makes all investments which are necessary and gives an energy saving guarantee. The partners then share the cost savings. The Senate of Berlin has successfully been implementing the model since 1996.

Renewable Energies

Sun, wind, water and renewable resources have a growing share in the supply of energy in Germany – meanwhile 10.3 percent. Today, a wide range of technologies and methods are available to produce power, heat or fuel from renewable energies.

Green IT

Computers, laptops, telephones, copiers and fax machines in offices and households are real power guzzlers. The same goes for computer centres. Meanwhile, approximately one tenth of the electric energy produced in Germany is consumed by information and communication technology (ICT).

Climate Protection

The rise of global average temperatures that has been observed for decades is mainly caused by the burning of fossil fuels such as coal, oil and gas. As a consequence, the protection of the fragile global climate has become a key task of government policy.

Combined Heat and Power

The simultaneous generation of power and heat in one plant is called combined heat and power (CHP) generation or cogeneration. Compared to separate production of heat and power in conventional power plants and individual heating systems, CHP units achieve an up to 40 percent higher efficiency. There are large and small plants operating on the CHP principle.

Mobility

50 million motor vehicles are registered in Germany, and there are also railway, planes and ships. More than 95 percent of today's traffic depends on petroleum-based fuels and causes about 20 percent of total CO2 emissions.

›› more

Photovoltaics

In 1905, Albert Einstein found a scientific explanation for the photovoltaic effect. Today, solar cells are producing more than 6,200 gigawatt hours of electricity per year in Germany alone. In contrast to solar thermal technology, photovoltaics (PV) do not use the heat radiated by the sun but its electromagnetic radiation (photons).

Solar thermal energy

In solar thermal systems, solar panels installed on the roof use solar power to produce heat. They may cover the hot drinking-water requirement of a house and support the heating system.

Environmental Education

What are renewable energies? How can you save energy? The aim of environmental education is to teach pro-environmental behaviour and the responsible handling of natural resources.
